What’s your citizen ‘trust score’?

Take George Orwell’s 1984. Now sprinkle in that episode of "Black Mirror" where characters live in a world in which every aspect of their lives is dominated by ratings. That’s one way to think about the Social Credit System, a plan that the Chinese government will make mandatory for all its citizens by 2020.

It’s like a credit score system, but instead of just financial information, this one will also pull together a person's political leanings, purchase history and even their social interactions to calculate their "trust score."
